I also think jumping spiders would be an amazing addition to grounded 2, but what i thought of when possibly adding them would having them as a pet like in the first game with aphids and weevils rather than a new buggie, they could be tamed with some sort of aphid soup made in the oven or something. Jumping spiders are known for making slack lines to catch themselves incase they miss their prey and then they can climb back up there web to try again, so I was thinking that the jumping spiders could latch to your back and act as a way to repel from builds and places in the environment. They could also potentially make single use ziplines/bridges by starting its web on one side of a gap and jumping to the other side and completing its zipline/bridge. I think this would fit perfectly with the upcoming update that will be adding ziplines.
